In situ biomonitoring using caged lumpfish (Cyclopterus lumpus) eggs reveal plastic and rubber associated chemicals in a harbour area in Central Norway

Figures & data

Figure 1. Concentrations of rubber and plastic associated chemicals accumulated in lumpfish eggs after exposure in the field at Brattørkaia (BK), Nyhavna (NH), Trondheimsfjorden (MH5: 5 m depth, MH15: 15 m depth), and in a transect from an aquaculture facility at the coast (ACE1 being closest). Significant differences (p < 0.05) between groups are denoted different letters (one-way ANOVA followed by Tukey’s multiple comparisons test).
